Two field experiments were conducted at Naguib Mahfouz village, Housh Eisa, El Beheara Government, Egypt. During 2019 and 2020 seasons, to study yield and its components of some half-diallel wheat bread crosses. A randomized complete block design (RCBD) with three replications was used. Each replicate consisted of 33 rows, 3 m. long and 30 cm in width. apart with 15 cm. between plants. Twenty grains were sown in each row.
Where the 7 parental genotypes (Sakha 94, Misr 1, Giza 168, Misr 2, Giza171, Sids 14 and Shandweil 1) were sown in the first season 2019, and crossbreeding took place among them together to obtain 21 hybrids resulting from that process. During the second season 2020, parental genotypes and their 21 F1's were also cultivated, and both parents and their 21 F1's were evaluated in terms of the crop and its components under the natural conditions of the field experiment.
The obtained results revealed that half diallel bread crosses between the seven Egyptian affected significantly for days of maturity (DM) , spikes number /plant (S/P),  1000 kernel weight (KW), grain yield/ row (GY/P), biological yield/ row  (BY/R), and Protein content (PC) .and the wheat cross (Sakha 94( P1)  x Giza 168(P3)) recorded the highest means values of above-mentioned characters and gave the highest yield and its components under this study.
